Amanita Design

Botanicula follows the adventure of five botanical creatures (named Mr. Lantern, Mr. Twig, Mr. Poppy Head, Mr. Feather and Mrs. Mushroom) that are trying to save the last seed of their home tree from evil parasitic creatures that have infested their home.
Like the previous games from Amanita Design, Botanicula follows the same scheme of gameplay where the player controls a protagonist (or multiple protagonists) while exploring the environment, solving puzzles and collecting items that are required for the obstacles that come in their way. The player is able to interact with other creatures and find easter eggs that are present in the lush environment.

A few minutes of gameplay from the great point ‘n click game Botanicula:

The goal of Machinarium is to solve a series of puzzles and brain teasers. The puzzles are linked together by an overworld consisting of a traditional “point and click” adventure story. The overworld’s most radical departure is that only objects within the player character’s reach can be clicked on.
Machinarium is notable in that it contains no dialogue, spoken or written, and apart from a few tutorial prompts on the first screen, is devoid of understandable language entirely. The game instead uses a system of animated thought bubbles. Easter egg back story scenes in the same format can only be revealed by idling in certain areas.
The game employs a two-tier hint system. Once per level, the player can receive a hint, which becomes increasingly vague as the game progresses. Machinarium also comes with a walkthrough, that can be accessed at any time by playing a minigame. As with dialogue, the walkthrough is not in written or spoken form, but instead a series of sketches describing the puzzle at hand and its solution. However, the walkthrough only reveals what must be done in that area, and not how that puzzle relates to the game chronology.
